Word filtering

Imagine that we want to extract all the hybrid cars from our database. As you understand, doing it manually is a worthless job and has to be automated.

Surely it has already been implemented! To filter observations based on columns with text use WHERE statement. For example,

SELECT *
FROM audi_cars
WHERE fueltype = 'Hybrid'
123
SELECT * FROM audi_cars WHERE fueltype = 'Hybrid'
copy

This query will return all the Hybrid cars.

Please note, that in that case, you have to use single quotes, not double!

Task

Swipe to start coding

From audi_cars table extract only cars with Automatic transmission. Extract all the columns.

Solution

SELECT *
FROM audi_cars
WHERE transmission = 'Automatic'

Everything was clear?

How can we improve it?

Thanks for your feedback!
